We have organized several common questions for our clientsmay help you sincerely

1.what price for each watt?

it depends on the quantity, delivery date and payment terms,

2.what is your size for each module? can you tell me the parameter of your module?

we have different series of panels in different output, both c-si and a-si. please take the specification sheet for your reference.

3.Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Yes, we can, we have two companies for solar region, one is CNBM International, the other is CNBM engineering Co.

We can provide you not only the solar module but also Solar Cells, the off grid solar system, we can also provide you service with on grid plant.

Q:what do we mean by efficiency of a solar panel?
Sunlight power panels had been the go-to choice for many years. They are among the many oldest, most efficient and most liable methods to produce electrical energy from the solar. Every module is made out of a single silicon crystal, and is more efficient, although more pricey, than the more moderen and less expensive polycrystalline and thin-film PV panel technologies. You can normally appreciate them through their color which is more often than not black or iridescent blue. The silicon crystals have lengthy existence and they may be able to withstand wear and tear with out degrading its workability. Additionally solar is a main source renewable vigour as far as the sunlight method is worried. Sunlight has little influence within the residing creature. So sun panel should be in practice
Q:Why are solar panels only 0% efficient?
Unlikely that we gan get to near 00% efficiency, although there is room for improvement. In the meantime, don't pooh-pooh 0% efficiency. That's about the rate of energy transfer up a food pyramid, perhaps a little less at the solar to plant level. As this manages to provide the basis for most of life on earth, it's nothing to sneeze at. As far as the other 90% goes, I would guess that much of it is reflected.
Q:What minerals are used in making solar panels?
Heating panels have aluminum for the frame, glass for the top, copper pipes running through them, and possibly some plastic parts. The raw materials are easily obtained. Copper is the most difficult to get probably, but it's not all that rare, since we used to make pennies out of it. A solar electric panel is similar, with the copper used for wires and interconnect instead of pipes. The actual solar cells commonly used are almost completely pure silicon, which is abundant worldwide. There are traces of other elements in the silicon like boron, arsenic or phosphorous - these are also inexpensive, and easy to get.
Q:who would win in this battle?
hmmmmm trees would squash em and solar pannels would electric cute em............... :)
Q:Solar Panels in Abu Dhabi, UAE?
I know where in Dubai , just go to Naif road where they sell the satellite equipment , there are a couple of shops that sell all kind of solar panels and dish equipment stuff. Sorry can't remember the name, But it is right in front of the paid parking lot (the private not public one).
Q:Where are solar panels used?
Solar panels are used to help reduce electricity you put them on your roof and you get the suns raze and that turns into solar electricity
Q:How much does a race car that uses solar panel cost?
thats an oxymoron/race car with solar power/forget it/by the by if they start to really harvest the available sources for power the retail price of gas will be 25cents a gallon/
Q:should i get a solar panel?
Solar power works by capturing photons from the sun and storing their energy in a battery. Solar panels still only capture a very small amount of photons due to technology/distance from the sun/ and probably a number of other reasons. If you wanted to buy a solar panel, you find a company that sells them, send them your electric bill for the past year or so. They calculate the energy restraints, size and additional technical mumbo jumbo. They tell you how much it costs and how much money you could save. Some people might buy a size larger than what they need, in which case they sell the excess energy to your local power company for a few pennies a month(this is usually not very profitable).
Q:I'm have a DIY solar panel and wanted to use micro inverters?
Have okorder.com . It might truly benefit anyone!
Q:Why should I use solar panels?
They are not necessary, and you don't have to use them. However, the benefit of using solar panels is that you can make your own electricity at no cost. Yeah, of course, you need to spend some cash to build those panels, but once they are there, they will work like a charm, giving you free power.
